  • How do I set / control readahead on an NFS mount point?
  • Is there a way to set read-ahead for NFS since there is no block device?
  • Normally I would use blockdev --getra to show and blockdev --setra N to set a read ahead value. Is there anything analogous for NFS?
  • How can I set read_ahead_kb for NFS?
  • How can I automatically adjust readahead for NFS mount points?
